I become an Air Canada member the benefits even though Maple Leaf Lounges are not a part of those benefits you do get a "discount" which means you get $5 worth of food for a $20plus entrance fee.
But the lounge it self is actually quite nice, it's very comfortable certainly better than sitting by the gate. It's quite and I must admit I have fallen a sleep on my seat more than once. The food even though I have complained about the price above is not bad, it's a continental breakfast, a working lunch, and a poor man's dinner but the choices at least are healthy.
When it comes to the services it's the usual WiFi, business area, sitting area and a dining area. The view of the Terminal 1 runways are not bad. You can stare out watching the planes land and take of. There is a lot of movement out there. I have enjoyed all my visits here.
